Pluto revisited

Not the frozen planet way out yonder, nor the Disney dog.

Project Pluto, which I talked about a couple of years ago, mostly in the context of the ramjet engine that was to be it's source of power.

For those needing a refresher, Pluto was to be a nuclear powered cruise missile, capable of Mach 3 at treetop level, dropping nuclear warheads in its wake. There were serious, ah, problems shall we say, with the concept. It was possible, but eventually people asked if it was desirable.

Thanks to Ghost of a Flea, we have a new link to a nicely detailed history of Project Pluto. Fascinating stuff.
